At GESmaterials, we provide high-performance Boron Nitride (BN) materials, available in both solid and powder forms, including Hexagonal Boron Nitride (h-BN) and Pyrolytic Boron Nitride (PBN). As an advanced synthetic ceramic, Boron Nitride is renowned for its unique combination of properties such as excellent electrical insulation, high thermal conductivity, superior dielectric strength, and remarkable oxidation resistance up to 800 ℃. Often referred to as “white graphene” or “inorganic graphite”, solid BN features a hexagonal platy crystal structure that delivers outstanding thermal shock resistance, high heat capacity, and easy machinability into complex shapes. In addition to its technical advantages, Boron Nitride is non-toxic and available as a colorless crystal or fine white powder, making it suitable for a wide range of demanding applications across electronics, metallurgy, aerospace, coatings, and other advanced industries. At GESmaterials, we are committed to providing reliable, high-purity BN solutions tailored to meet the requirements of modern high-tech manufacturing.
At GESmaterials, we supply Boron Nitride (BN), a unique material available in several crystalline forms (hexagonal, cubic, and wurtzite), each offering distinct properties. With high thermal conductivity, excellent dielectric strength, chemical inertness, and lubricating ability, BN is widely applied across advanced industries.
Electronics: BN provides thermal management and insulation in electronic devices. It is used for heat sinks, insulating components, dielectric substrates, and as a support material for high-performance electronics.
Cosmetics: Owing to its low friction and inert nature, BN is incorporated into cosmetic formulations, giving products a smooth texture and soft skin feel.
Aerospace: BN’s thermal stability makes it valuable in aerospace applications, including rocket nozzles, heat shields, and high-temperature structural components.
Dental & Medical: With biocompatibility and heat resistance, BN is used in dental tools and other medical components requiring durability and precision.
Ceramic Manufacturing: BN ceramics are ideal for kiln furniture, crucibles, and refractory parts, offering stability in aggressive high-temperature environments.
Nanotechnology: Boron nitride nanotubes (BNNTs) are being developed as reinforcements in composites, with potential applications in nanoelectronics and advanced materials.
BN Crucibles: Hexagonal BN (H-BN) is commonly used for crucibles in high-temperature material processing and laboratory experiments.
Abrasives & Heat Spreaders: Cubic BN (C-BN) is a top-tier abrasive for cutting and grinding tools, while also serving as an excellent material for heat spreaders.
Dielectric Substrate: Wurtzite BN (W-BN) is considered an advanced dielectric material for optical, electronic, and graphene-based devices.
